EASEL.

SPECIFICATION forming part of Letters Patent No. 486,549, dated November22, 1892.

Application filed February 23, 1892. Serial No. 422,695. (No model.)

T0 all whom t Wwty concern.-

Be it known that I, ANDERS C. TERsLosE, a subject ot the King ofDenmark, but hav- -ing declared my intention kto become a citizen of theUnitedStates of America, and residing at St. Paul, in 'the county ofRamsey and State of Minnesota, have invented certain new and usefulImprovements in Easels'and Easel Attachments, of which the following isa speciiication, reference being had therein to the accompanyingdrawings.

My invention relates to easels; and it consists in certain novel meansof connecting and adj usting the several parts and in means forsupporting the canvas or p icture.

The object of my invention is to providea simple and convenient devicefor the use of artists in doing iield work, but which may be used forother purposes to which it may be found adapted.

In the accompanying drawings,which form a part of this specification,Figure l is a perspective view showing one of my improved easels as itwill appear when ready for use. Fig. 2 is a perspective view showing thecanvas support and clamp when disconnected from the tripod. Fig. 3 is adetail in crosssection of the tripod, showing the manner of attachingthe brace. Fig. 4 is a detail in vertical section of the upper portionof the tripod, showing how the parts are connected. Fig. 5 is a detailwith one leg of the tripod removed, showing the head-piece incross-section and the pivoting of the central leg. Fig. 6 is aperspective view of the head-piece. Fig. 7 is a modified form of thecanvas-clamp, shown in perspective; and Fig. 8 is a side view of thesame.

In the drawings, a c a? indicate the legs of the tripod, and b aspring-brace by which the legs are held extended.

c indicates a spring-clasp for holdinga canvas or picture frame toprevent its displacement or to adjust it to suit the light.

d indicates a rod for attaching the clasp to the tripod by means of thehooked end CZ', the adjustable spring-clamp e, the rod g, and the wireloops f f', the legs of the tripod being secured at the top by thehead-piece h.

The legs d a are provided with a series of holes, into which are tittedpins t' which support a grooved board r, upon which the lower A part ofthe picture or canvas frame rests. It will be seen that if a picture orcanvas frame is made to rest in the groove r of the board r and theupper edge be pressed between the lingers t t of the clasp c it can beeasily adjusted to any position the artist may desire by drawing the rodgback and forth through loops ff', or by giving the rod g a rotarymovement around the rod d it will also be observed that the groove r isadapted to prevent the base of the picture or canvas frame from slippingafter being inserted therein by being formed with one sloping and onevertical side.

To adj ust the holder c to frames of variable height, the rod d is madewith one of its attachingclamps adj ustably connected therewith bymaking it of spring-wire and bending it in such a manner as to cause itto hug the rod d closely. The clasp is shown in the drawings as beingmade of a single piece of wire, one end of which is formed into aneye,which the rod d passes through. The wire is then passed along therod for two or three inches and again formed into an eye, which fits therod closely. It is then extended at right angles from the roda distancecorresponding to the thickness of the leg of the tripod to which it isto be attached, when it is again bent back nearly parallel with the rodd, the arm formed by this last bend being given a bend first in thedirection of the rod d and then from it, so as to adaptit to bind thetripod when attached to it. It will be observed that by adjusting theclamp e along the rod d the whole device may be moved up or down thetripod and be made to conform to the widening or the divergent linesformed by the legs, as the case may be. pod is made rigid when set up isalso formed, as shown in Fig. 3, of a single piece of springwire bent toform an eye and two outwardlyextending arms. The eye is to secure it tothe leg a? of the tripod by a` staple or in any suitable manner. Thearms extend outwardly, so that it is necessary to compress them beforethey can be inserted between the legs a a of the tripod, the legs beinglimited in their outward movement by the central part of the head-piece72, as shown in Fig. 4. It will thus The spring-brace by which the tri-lIOO be seen that if the legs of the tripod be separated as far as thehinge will permit and the arms of the brace b be contracted and insertedinthe holes on the inside of the legs, as shown in Fig. 3, the tripodwill be rigidly secured in its extended form, as illustrated in Fig. 1.The part h, in which the legs of the tripod are pivoted, is formed of anintegrai piece consisting of the front plate h and two Vangular wings h2h3. Between the front plate and the sides of the wings parallel theretothe legs a a of the tripod are pivoted, the leg a2 being pivoted betweenthe wings as they extend at right angles from the main plate, the innersurface being formed smooth for this purpose and the opposite sidesbeing beveled, as shown in Fig. 4, to accommodate the movement of thelegs a a.

Figs. 4 and 5 illustrate the method of pivotin g the legs of the tripodto the head-piece 7L.

Figs. 7 and 8 show a modified form of the clasp c, that may be usedinstead of the one above described, which is made of spring-wire. In thelast-named figures, k indicates a plate having a central slot, throughwhich passes the shank of a thumb-screw n. The plate k has adownwardly-extending jaws, which cooperates with a movable jaw m to holdthe picture or canvas frame when placed between them, the jawm beingmade to close upon the frame byineans of the thumb-screw, said jaw beingprovided with an inwardly-extending lug m', which iits the slot in plate7c, the lug being perforated and provided with a thread, which takes theshank of the thumb-screw n, by means of which the jaw can be made totraverse the plate 7c in the direction of the slot.

p p are two oppositely-disposed posts attached to or formed integralwith the plate 7c, having their upper ends perforated to receive the rodg, as in the case of the wire clasp.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. An easel consisting of the legs a a a2, head-piece h, and brace b,the legs a a being provided with holes and iitted with pins t' i, iucombination with a board r, provided with a groove 1", one side of whichis inclined and the other vertical, substantially as described.

2. In an easel, a tripod consisting ot' the parts a a a2, connectinghead piece h, and spring-brace b, substantially as described.

The combination of the tripod and rod d, adjustably connected thereto,with the clasp c and rod g, the rod g being adjustably connected to therod d and to the clasp, substantially as described.

4.-. The combination of the rod d with the adjustable attaching devicee, consisting of a wire bent so as to form two eyes and aspring by whichit is secured to said rod, substantially as described.

5. The combination of the rod d with the clamping device e, providedwith the arm e', the device being adj ustably connected to the rod,adapting it to adjustment upon the easel, substantially as described.

In testimony whereofI afiix my signature in presence of two witnesses.
